Audi has an excellent sporting sedan with its updated S4. There’s a problem though, and it exists within the automaker’s own family. It’s called the Audi RS3.

Which would you choose if you were in the market for such a car? The S4 has more room and can be had for less depending on how its spec’d. The RS3 makes 400 horsepower from its inline five-cylinder engine, awesome noise from its exhaust, and features RS-tuned suspension, steering, and quattro all-wheel-drive.

You’re not going to wind up with a bad car, no matter which one wins your heart (and cash). You might be reconsidering though, anytime you find yourself next to the other in traffic.
